I have already asked some questions that concern the Suggestion spell (here and here). However, there are still some aspects of this spell that are not clear to me. In particular, the fact that the course of action must sound reasonable can be ambiguous. According to the manual, you cannot ask a target to stab himself, but you can ask him to give his horse to a random person. Now, consider for example the following situations:
- A halfling is carrying a magical ring that could be extremely dangerous if it was in wrong hands. A wizard suggests him to give it to the first person he meets.
- A young seaman has just been given a giant vessel and he is going to set sail, the dream of his life. A wizard suggests him to sell him the vessel for a few money.
can the Suggestion spell be used in these situations? Can these courses of action be considered as reasonable? In general, how to quickly determine if the course of action is reasonable?
